Red Bay Ambrosia Beetles A Problem For Several Tree Species

Natural Wakulla by Les Harrison

Spring 2018, it appears from all the weather signs, has sprung. After last year’s late frost sneak attack there is lingering concern that a destructive weather event will reoccur, but with each passing day that likelihood diminishes.

Plants are budding, blooming and leafing out all over Wakulla County, with a notable exception. Many red bay trees remain in what appears to be winter’s grip of dormancy.

Unfortunately, most will never reawaken. One little insect in the Xyleborini tribe of beetles has been destroying bay trees and other species at an alarming rate.

This red bay tree on Commerce Boulevard will not leaf out this spring, or ever again. Redbay Ambrosia beetles have infected it with laurel wilt disease which has killed it.

Ambrosia beetles are known for attacking various woody plants, causing some limb and stem dieback and sometimes plant death. There are at least 30 species of ambrosia beetles in Florida, several of which are non-native.

The Beetles Consume Fungal Food

Typically ambrosia beetles have a symbiotic relationship with a fungus with the beetles carry fungal spores on their bodies. When the beetles bore into the sapwood of the host tree, the galleries formed from the beetle boring are inoculated with the fungal spores.

As these beetles continue their damage the spores germinate and infect the host tissue. The fungus flourishes in the galleries and adjacent sapwood, disrupting the flow of water and nutrients in the tree.

As the fungus grows the beetles and their larvae feed on it and spread the new spores. It is a perfect example of a self-sustaining species which grow its own food.

Most ambrosia beetles attack trees and shrubs which are already stressed, dying, or dead. Plant stress may have been initiated by drought, flooding, freezing temperature damage, wind damage, or very poor cultural practices. It is nature’s way of renewing itself for the strong and productive.

Unfortunately, some ambrosia beetles, such as the Redbay Ambrosia Beetle attack healthy trees. Of additional importance, the fungus which causes laurel wilt accompanies this beetle and typically causes tree death.

What Do They Look Like?

The Redbay Ambrosia Beetle (Xyleborus glabratus) is a very small, about 2 millimeters in length or 15 could fit head to toe in an inch. They are dark brown to black, cylinder-shaped beetle, similar to other ambrosia beetle species found in Florida.

The adult female Redbay Ambrosia Beetle has a special pouch in its mouth which transports the spores of the fungus responsible for laurel wilt disease (Raffaelea lauricola). When these beetles bore into the wood, forming galleries, the spores transported in its mouth and on its body infect the tree.

As this pathogen germinates, it colonizes the sapwood of the host plant by using the tree’s circulatory system to spread the disease. Unfortunately, the tree is usually doomed at this point.

The Ambrosia Beetles Origins

The Redbay Ambrosia Beetle is native to East Asia, but the origin of the destructive fungus accompanying the beetle is not known. The beetle is believed to have been inadvertently released into Georgia in 2002 through infested packing materials, such as wooden crates and pallets.

Several species of bay trees, sassafras and avocado trees area all potential host for this imported pest. At present there are no registered fungicides for avocado that will control laurel wilt.

The best control measures are to not bring in wooden pallets and other similar products which may carry the tiny beetles, their larvae and the fungus. Firewood from distant sources is another potential carrier of this problem species.

Attention to these details may save many great trees in Wakulla County, and hopefully beyond. The loss of bay and sassafras trees will change the area forever, and not for the better.

You wrote a very funny story for a very sad plant issue. I wish you had let the readers know just how invasive and horrible Mexican Petunia is. It is taking over Florida, and is (as you mentioned), very difficult to exterminate. It is a Category I FLEPPC invasive here and should be illegal to grow. I hope things get better for you and your yard. St. George Island is where my wife and I went on our honeymoon. I've never forgotten it. It's a very special place indeed! You're a lucky man!!

Thank you for the information. I learned in our Franklin County MGV class that my wife had planted three specimen Hamelia patens in our south facing yard on St. George Island. I am going back today to weed and put landscape cloth around them so they can thrive. Also liked seeing examples of your MGV blogs, thanks.

Our article was written with the northern panhandle yard in mind where firebush is close to its northern limit. In central Florida, you can maintain your shrub at full size year round. We cut them back in late spring here because our winter temperatures freeze them. It sounds like you have the dwarf firebush and that will stay in the 8-10' range. They can be cut back during the winter months if the size out grows your area. For more information, you can contact your local county horticulture agent. Thanks for the comment and good luck with your plant. They really are amazing plants for attracting wildlife.

I have two hamelia patens in my yard and they're about 8' tall. This is in central Florida so that may make a difference. It is without a doubt the most popular plant in the landscape for birds and pollinators. Bees and wasps go nuts on them all day long. Quite a show to behold! Are you saying it's ok to cut them down to 6" above ground, or cut 6" off the top of each stem or branch? Thanks for the article!

Great article. We own a snake control - snake removal business in Johns Creek, GA and I preach all the time to people to allow us to leave non-venomous snakes in their yard - especially Rat Snakes and Kingsnakes. First of all, Rat Snakes are Mother Nature's Pest Control which means they keep the rodent population in check naturally. Secondly, Kingsnakes eat venomous Copperhead snakes which are prolific in our area. So there are many benefits to leaving certain snakes in your yard. They can be beneficial.

Here is advice from the extension service in Prince George County, Maryland: Wild grape vines are native and good for wildlife, but they are rampant growers! ('Invasive' usually means a foreign invading plant these days.) So they can be a real problem in home landscapes. The easiest way to handle them is to cut them down at the base and IMMEDIATELY treat the freshly cut stump with an herbicide with glyphosate or triclopyr. Do not let the herbicide get on the trunks of your trees (or anything but the vine). You can use a shield of cardboard or plastic to keep the spray off your desirable plants. You don't have to remove the vine from the tree. It will decompose in place, but it is heavy, so you may want to remove it at least as high as you can easily reach. This is a plant with a big root system with lots of energy reserves. It will probably start sending up new shoots quickly or next spring. Spray them immediately with the herbicide. (Do not get any spray on the trees or other desirable plants) The leaves absorb more of the herbicide, so they are actually helpful in getting the herbicide to the root system. Both the herbicides are systemic, which means they will be absorbed into the system of the plant and translocated down to the root system. Spraying shoots in the fall is especially effective. It may take a while to exhaust the energy reserves and get enough herbicide down to the roots, but just be persistent. It will happen.

I am also including a link to a detailed publication by the University of Florida that includes more information about pre- and post-emergent control of nut sedges. http://edis.ifas.ufl.edu/pdffiles/EP/EP56900.pdf Our Master Gardeners have used the ‘Dismiss’ brand with sulfentrazone with decent results. It does need to be re-applied 3-4 times for good results. If you have any questions or suggestions for future articles please email to wakullamg@ifas.ufl.edu

November 19, 2019

Joshua – The pre-emergent herbicide you use depends on the types of weeds you wish to control. Broadleaf weeds like dandelions are different from the purple and yellow nut sedges, and therefore you will use two different pre-emergent herbicides. I am attaching a publication by the University of Florida about nut sedges, and towards the end of the document is information about pre- and post-emergent herbicides. http://edis.ifas.ufl.edu/pdffiles/EP/EP56900.pdf You will want to apply a pre-emergent herbicide before the weeds begin to germinate and appear in your lawn. For the cool season broadleaf weeds like dandelion, betony, henbit, etc. It is best to apply this in late October or early November and then do a second application in late December or early January. For warm season broadleaf weeds and sedges, you will want to apply the herbicide in late February or early March. Be sure to read the label to make sure the herbicide you apply will be safe to use on your particular lawn type.

Here is the link:: https://extension.uga.edu/publications/detail.html?number=C867-2&title=Controlling%20Greenbrier An herbicide with the active ingredient being either glyphosate or triclopyr works best.

While lubbers are in this nymph stage (small, black with yellow stripe) is the best time to get rid of these as the adults are much more difficult to eradicate. Options include pesticides that have one or more of the following ingredients; carbaryl, bifenthrin, cyphalothrin, permethrin or esfenvalerate. Other options include diatomaceous earth which can be dusted over the insects as they are active. Diatomaceous earth is harmless to the lawn and deadly to the grasshoppers.

Cathy, It is difficult to be sure of the species when common names are used. What we call it Florida might be (but not always) something different than the name used in Indiana. That said, your information indicates the unfortunate man had an encounter with spiny pigweed. This agronomic pest, also known as spiny amaranth, has abundant and very sharp thorns. Your continuing pokeweed problem is likely seed which are germinating from previous plants. One plant can produce hundreds of seed which are capable of lying dormant in the soil waiting for favorable sprouting conditions. Your persistence will be required to control this weed. Les G.L.

A TV station reported this week of a man that got skin damage by disposing of a weed he called hogweed or pigweed. the leaves brushed his face when he was cutting it out. could this be pokeweed? I have been fighting pokeweed in our yard for the past 2 years. I first noticed it growing behind the shed. I was fascinated by the largeness of the stem and then the flowers. When I looked it up and found it was a poisonous pant I cut it down and sprayed it well to kill the root. Since then I see plants pop up all over the place. I live in Indianapolis, IN.

Hello Ms. Gail, sorry for the delayed response. Deer moss is a lichen species, a symbiotic relationship between a fungus and algae. Under the right environmental conditions they grow, albeit slowly. When the growing conditions are not favorable deer moss degrades and becomes less visible, usually residing under leaf litter and other forest debris. Also, fire from a controlled burn (or any other source) will kill lichens. Let us know if you have further questions!

Gail Doukas

Thanks. I will go to the website and email address you gave me. I had just read an article in the Gulf Breeze News about a coral snake in someone's front yard. I think the police, who responded to the homeowner's call, could have done something other than hack the snake to death. I had a coral snake in my yard several years ago, and I was fascinated: I waited it out and finally it moved on. I would have have acted differently if my over-eager dog wanting to catch it was out there with me! I just wanted to see if there is some guide for responders to snake calls.

Sigrid, I would recommend you add your email to the "Panhandle Outdoors" newsletter/blog.

You can also contact him directly at roc1@ufl.edu for specific questions. There's lots of information available on this topic; however reducing a long-held fear is often more difficult than teaching folks to properly identify them. http://edis.ifas.ufl.edu/topic_series_dealing_with_snakes_in_floridas_residential_areas

Sigrid Benson
October 23, 2014

So you recommend killing armadillos? What's the most humane way to do that? And by the way, when a coral snake comes in your yard, it is NOT a time to panic, as one homeowner did in Gulf Breeze last week. The responding policeman used a hoe to beat and hack the poor snake to death. What do you recommend for coral snakes (who are not that aggressive) and truly aggressive snakes like rattlers? Are there any applicable pamphlets I could get so we could make sure the police and fire departments get to learn the best way to handle those situations with hysterical homeonwers?

There are two herbicides that can be used to control horse nettles: the best choice is GrazonNext, and the other option is Remedy. Both products have a zero day grazing restriction, so they can be sprayed with the horses in the pasture. If the horse nettles are not everywhere you can spot treat the weeds and greatly reduce bot the cost and exposure to the herbicides. The GrazonNext is the preferred product, because it not only kills the weds, but also will control seedlings that emerge for several months after application.

Sally thank you for your interest. We have several articles on cogongrass on our ag site and in our archives. See the links below for more information. COGON GRASS ARTICLE: ID and Control of Cogongrass Cogongrass web site Cogongrass is best controlled with mixtures of glyphosate and imazapyr. This is typically done in pine forests, right of way areas or pastures. Home gardeners need to be careful when using such products since these herbicides will kill broadleaf perennials, shrubs and annuals. The only method I'd recommennd would be careful spot treatment with glyphosate by brushing on the product. Do not get any on the desirable plant material and follow all label directions. Do not incorporate imazapyr into the mix since it will keep the area bare for 6 months. The other alternative is to kill everything and start over once the cogongrass is 100% eradicated.

Hello Joyce, Unfortunately, there is not a selective herbicide for the vine that will not harm the shrub as well. What I have had success with in the past is to wick or paint glyphosate (also sold as roundup, under many other names as well) on to the leaves of the vine, while being careful to not get even one drop on the desirable shrub. This may need to be repeated 2-3 times. It worked well for me. Always follow label directions when mixing and wear appropriate clothing according to the label directions. It is more effective in warmer weather.

I have this vine in a few of my shrubs. I try to pull it out, but don't get the roots as they are deep within the shrub. Is there a herbecide I can use on the vine that won't harm the shrub? If not, how do I get rid of it?

I wish you would include a discussion of Cogongrass which is listed as one of the (if not #1) most noxious weeds in the world. I have it and it appeared after Hurricane Ivan. I have tried everything I have read about it to remove it, without success. I am desperate as it is now in my flower garden. Will appreciate any suggestions!

If you can find it; Carya aquatica, Water Hickory, would be your best choice. Read more by following this link for a publication on Water Hickory.

My home is at the top of Escambia Bay, very poor soil. There's a small creek that runs through my property into the bay. I think in the past we may have had hickory trees growing down near the water, but I don't know what kind. Which of the three would you suggest for my site? Appreciate your help!
